Profiling: Improve !defined(PETSC_USE_LOG) #defines

- If we cast macro arguments to void, we can avoid unused errors that have
forced lots of conditionally included code like this:

```c
#if def

Profiling: Improve !defined(PETSC_USE_LOG) #defines

- If we cast macro arguments to void, we can avoid unused errors that have
forced lots of conditionally included code like this:

```c
#if defined(PETSC_USE_LOG)
PetscLogEvent event;
#endif
```

- Having global counters like petsc_TotalFlops externed event
if !PetscDefined(USE_LOG) helps to remove a lot of needless
`#ifdef`s around code that can instead be placed in
`if (PetscDefined(USE_LOG)) {}` blocks.

Fix make check when --prefix points to a read-only file system

In general make check should not be writing anything in a directory indicated by $PETSC_DIR since that is where PETSc is installed.

Satish, we should have a make install that then uses chmod u-w newpetscdir ; make check to verify this bug never reappears

Specifically, removes translated Fortran and Algol routines which had non-terminating loops if assumptions were violated with a standard LAPACK eigenvalue solver routine. Add new alternatives due to minor differences in eigenvalue estimates.
